MICHAEL OCONNOR, OF NEW BRUN SW'ICK, NEW JERSEY.

FAucET-SCREW.

SPECIFICATION forming part; of Letters Patent No..295,794, dated March 25, 1884-'.

` Application tiled January 19,"188-1. (No model.)

spout, combined with a-screw fitting thesocket,

and having a valve at its inner end and a head at its outer end for closing or opening the inner end of the spout.

The object of my invention is 'to simplifythe .construction of such devices and reduce the cost of manufacture.

To such end the invention consists in the construction and combination of parts hereinafter described and claimed, and illustrated in the accompanying drawings, in which- Figure l represents a sectional view of my faucet-screw when the valve is closed. Fig. 2 is a vertical central'section of the same when the valve is open. Fig. 3 is a plan o1: top view of the same. Fig. 4c is a section of the valvebody detached.

Similar letters indicate corresponding parts.

In the drawings, the'letter A designates a metallic plate which serves to attach the screwfaucet to a sheet-metal can, and which is provided with a sheet-metal screw-socket, a, the inner end of which is enlarged so as to form a chamber, b, from which extends the dischargespout B. The plate, the chamber, and the screw-socket are all formed out of one and the same piece of sheet metal.

lIhe letter C designates the valve, the body of which is composed of a sheet-metal screwstem, c, from the inner or open end of which projects a ilange, d, (best seen in Fig. 4,) said screw-stem and flange being made out of one and the same piece of sheet metal. With the flange is combined a sheet-metal cap, e, which serves to strengthen the saine, and on said flange is placed a packing-piece, f, of any material suitable for the purpose. The screwstem c Iits the sheet-metal screw-socket a in the plate A, and after the same has been screwed into said socket a thumb-piece, g, is soldered or otherwise secured to its` closed end. The plate A is intended to be'soldered upon a sheet-metal can which contains oil or other liquid, and which is provided with an opening large enough to admit the valve C. When the thumb-piece g is turned so as to open the valve, (see Figa-2,) the chamber b is opened all round, anda free discharge of the liquid in the can through the discharge-spout is obtained. When the thumb-piece is turned so as to'close the valve, the packing f is drawn up tight against the inner surface of the attaching-plate A, and it is held firmly in this position.

In manufacturing the valve-body, the sheetmetal screw-stem becomes slightly tapering, the end nearest to the flange d being the largest, and as'the valve is closed this large portion of the screw-stem is gradually drawn up into the screw-socket, so that the threads are not liable to strip even if the valve is drawn up against its scat with great force.

The hat ati aching-plate being formed in one piece of sheet metal with the elevated chainber and the screw-socket, the cost of manufacture is reduced and the screw-threads will not strip.

What I claim as new, and desire to secure by Letters Patent, is-

l. The attaching-plate A, including in one piece the elevated chamber b, formed directly at the inner end of the screw-socket, and the valve-seat h, and having the nozzle and the threaded valve-stem and the valve arranged to pla-y in the socket and bear upon the seat of the attaching-plate, as and for the purpose described.

2. The attaching-plate A, adapted to be secured to a can, and including in one piece of sheet metal the screw-socket, and directly at its inner end the elevated chamber b and the valve-seat h, and having the nozzle B, said socket containing the screw-stem, having a thumb-piece at its 'outer end, and a valved inner end arranged to close over the chamber b and bear against the seat on the attachingplate, substantially as shown and described.

In testimony whereof I have hereunto set my hand and seal in the presence of two subscribing witnesses.
